Mark Zuckerman of CSNWashington.com reports that the recovery timetable is six weeks, so barring any setbacks Zimmerman should have plenty of time to get healthy for spring training.

Prior to his first injection Zimmerman hit just .218 with three homers and a .590 OPS in 55 games, but he hit .321 with 22 homers and a .967 OPS in his final 90 games to finish the year with an .824 OPS that’s right in line with his .832 career mark.

Hahaha! Yeah.
Although his trowing motion is certainly unorthodoxed (even off-kilter it seems)…dude is a solid 3rd Baseman.
If I were a Nationals fan I would hope the surgery does nothing to fix that motion.
It obviously works for him.
